It is quite well known that Clemenceau sabotaged the peace conference with the Bolsheviks. He doesn't mention Lenin's name in this text- not even once. Lenin was the best option for a Russian head of state, according to the US Ambassador- who was so disgusted with Clemenceau and the other allies (including Wilson, eventually) that he quit his job on the spot. Clemenceau was a toad of a man! I feel bad for Lady Violet Maxse, who dated him.

This is what he failed to mention, in more detail:

The Bullitt Mission to Soviet Russia, 1919
In March of 1919, William Christian Bullitt, an attache to the U.S. delegation to the Paris Peace Conference, visited Soviet Russia on a clandestine mission. Although Secretary of State Robert Lansing only authorized him to report on political and economic conditions, Bullitt's actual objective was far more ambitious: to broker an agreement between the Allies and Russia's Bolshevik government that would end the Russian Civil War, lift the Allied blockade of that country, and allow the Allies to withdraw the troops they had dispatched to Russia in 1918. Bullitt eventually received a proposal from the Bolshevik government that would have realized these goals, but the Allied leaders at the Paris Peace Conference were unwilling to accept the offer.

Following the withdrawal of Allied diplomats from Petrograd and Moscow in 1918, the Allied leaders - U.S. President Woodrow Wilson, British Prime Minister David Lloyd George, French Prime Minister Georges Clemenceau, and Italian Prime Minister Vittorio Emmanuele Orlando - grappled with the question of how to address the Russian Civil War that had broken out between the Bolsheviks and White Russian forces following the Russian Revolution. After the signing of the Treaty of Brest-Litovsk in March of 1918, Allied, Japanese, and U.S. troops had occupied parts of Northern Russia, the Ukraine, and Siberia


Bullitt returned to Paris on March 25, and there faced Allied resistance to the proposal he received from Lenin. Although Lloyd George privately assured Bullitt that he was sympathetic to the Bolsheviks' offer, he repudiated it once news of Bullitt's mission had been leaked to the British press. Clemenceau had opposed any overtures to Lenin from the start. Wilson was in poor health and was focused on achieving a breakthrough in negotiations with the French concerning the peace treaty with Germany. Furthermore, the President's relations with House, Bullitt's original patron, had soured greatly. Finally, news from Russia indicated that anti-Bolshevik forces would soon capture Moscow, thus obviating the need to negotiate with Lenin. Consequently, the April 10th deadline for the Allies to respond to Lenin's offer passed without any word from the Allied side, and Bullitt angrily resigned from the U.S. delegation on May 17. The failure of the Allies to agree to the proposal secured by the Bullitt mission delayed official U.S. recognition of Soviet Russia for many years.
